similar to Fig. 3 after a blade has been transferred from the magazine to the blade holder,

Fig. 5 is a fragmentary section similar, to Figs. 3 and 4 with the key. or wedge:- member of the is inserted. A bowed leaf spring I4 positioned above the clip of new blades in the magazine holds the blades firmly against the partition II. A slide I 5 reciprocable by means of sideplates I5a longitudinally of the injector body is supported in slots I) in the side walls of the body. The

slide is located immediately below partition II.

The partition is centrally slotted to accommodate a web I6a punched from the ejector plate It which connects the plate to the slide I5. The slide in its retracted position shown in Fig. 3 is directly behind the end of the bottom blade of the stack of blades in the magazine. When the slide is moved longitudinally of the body, the front edge of plate I6 abutting the end of the blade slides it along partitions II into the gripping members I3 of the holder. Extending from the front of the slide is a flexible hook shaped member II adapted to. engage a slotted opening I2a formed in theen'ds of the blades. furcated ends of partition I I are flexible and are slightly upturned, as shown at I la, to direct the travel of the blades from the magazine to the holder and from the holder to the disposal compartment, as well as depress hook I'I while a new blade is being inserted in the holder.

The functioning of'the device should be obvious from the description and drawings. The wedge I 00 of the injector is slipped into the back of the blade holder between the flexibly mounted blade holding members I3. This spreads the members and permits easy insertion of a blade. Slide I5 is retracted to the end of the body as shown in Fig. 3 behind the bottom blade in the magazine. In this position hook II is depressed slightly below partition II. The slide is then advanced toward the holder, plate l6 abutting the end of the blade moves it along the slotted partition I I and between the blade holdingmembers I3 of the holder. As the blade passes through theaperture in the body adjacent the holder the upturned ends Ila of the partition, as well as the hook II, are depressed beneath the blade as shown in Fig. 4. Depression of the hook causes it to pass beneath the lower blade holding member as the new blade is inserted into the holder. The wedge of the injector may now be removed frori engagement with the holder and the razor use To remove the blade from the holder and insert a new blade, the wedge is again fitted into the holder as shown in Fig. 5. It will be noted that the hook I7 is now in a raised position since upturned member IIa has sprung back after the passage of the blade into the holder. With complete insertion of the key or wedge, hook I! overrides the top of the blade and drops into aperture I 2a (see Fig. 6). Retraotion of'the slide as shown in Fig. '7 withdraws the blade from the holder and passes it beneath the upturned ends Ha of the partition. With the rearward stroke of the slide the used blade is withdrawn int-o disposal compartment IBb. At the end of the blade withdrawal stroke slide I5 is in the position shown in Fig. 3, ready to insert a new blade into the holder.

The bi- In the modification shown in Figs. 9, 10 and 11, the front of plate I6 is hook-shaped as shown at l6b. It has an arched shape and during its travel beneath the stack of blades in the magazine it assumes a horizontal position as shown in Fig. 9. The front end of the hook abuts the end of the bottom blade in the magazine and transfers it from the magazine to the holder as the slide is moved longitudinally of the body. In Fig. 9 the slide is shown in its advanced position when the new blade has been pushed home between gripping members I3 of the holder.

To remove the blade from the holder the injector wedge Illc is removed or partially removed from 1 the holder as shown in Fig. 10. The slide is then advanced so the hooked end of the .plate lBb is permitted to arch upwardly as shown in Fig. 10.

The wedge of the injector is again pushed home in the holder as shown in Fig. 11, causing hook 16b to override the top of the blade and engages aperture I-2a. Retraction of. the slide pulls the used blade into the disposal compartment IOb as before.

In the second modification shown lnFigs. 12 to 16, inclusive, an ejector plate I8 located between the holding members I3 of the razor ejects the used blade from the holder, serving the function of the hooked members of the slide. In this second modification the body member, and wedge of the injector and blade disposal device are similar in construction; to the preceding types. The body member In is divided centrally by partition II into an upper magazine Illa and a lower blade disposal compartment Ilib. The slide, however, consists of aplate l5 below thepartition and a blade abutment plate IE above the partition reciprocable in slots "10f, The partition II has bifurcated upturned ends I'Ia as before.

An ejector plate-J8 reciprocable in a narrow passageway between the, upper flanges of the blade holding members is shown in Figs. 12, 13 and 16. Ejector I8 is manually moved across the head of the holder by meansof button I9 attached to the ejector plateby a narrow neck which extends through slotted opening 20 at the back of the razor head. V r

To insert a blade from the magazine to the holder in this modification the slide I5 is retracted until the edge of plate I6 abuts the end of the bottom blade in the magazine as shown in Fig. 13. The slide is then'advanced and the bottom blade moved into the holder as shown in Fig. 15. During the 'transfer of the blade the upturned ends I la of the magazine are depressed.

, After the blade has been inserted into the holder the ends I la of the partition-spring up and take the position shown in Fig. 14.. IWith the blade lodged in the razor headbetween the blade holding members, ejector plate 'IB:1ebuts the opposite end of the blade. To eject-the blade from the razor head ejector plate Ill-is manually slid toward the injector and blade disposal device moving the blade withit in the'direction shown by the arrow in Fig. 14. The blade is directed beheath upturned members Ila and into the disposal compartment labor the injector.

By these three difierent structures, a used blade may be withdrawn from the blade holding head of a razor into the disposal compartment of the injector and a new blade discharged from the magazine into 1 the razor headjwithout :manually handling either. Furthermdfepthere is not'only provided an enclosed-magazine for the new blades, but a simple, compact and safe disposal container for the used blades. ,j f

From th e'foregoing it will be seeri that this invention is one well adaptedtg attain all oi the ends and objects hereinaboveset forth together with other, advantages which are obvious and which areinherent to the structure, v;
